Hy cowman79, the casting number FE-18289 I believe should be 19289 and that comes back to parts for 16" brakes. The other number FE-20551 comes back to a left hand bracket for 15" brakes. which bracket(s) do you need, upper or lower right hand or left hand, right hand brackets have the slot for the adjusting wheel on the right side when viewed from the installed position, left hand is opposite. The casting numbers appear to be the same for upper and lower brackets. If you can tell me which hand and which position I may be able to come up with some part numbers for you.
